My second bag contains my offspec gear. My druid's current offspec is balance so I have spell leather in there. My third bag is where the stuff really starts to pile in. First, you'll find potions, flasks and food. You'll also find alternate pieces of gear that I may use situationally. After that the quest items and other random pickups start to fill in. My fourth bag is usually picked up items, and my fifth bag is also picked up items.
In my bank you can find tons of items that I need to get rid off. There are bags that are soulbound and smaller than my current bags. There are things that I need to put on the auction house but have been to lazy to. There are old crafting materials, in case I need to make something for an alt. Other items include
- lockboxes even though I'm not a rogue
- tabards I don't need anymore
- rep items
- food that I don't eat
- an ogre tannin
- a rock
